The Feast Conference is a social innovation summit gathering some of the world's most compelling thinkers and doers from a cross-disciplinary spectrum of innovation, inspiration and empowerment. Last year, The Feast featured an impressive roster of thought-leaders across design, entrepreneurship, economics, mobile and more, including 2.0 doctor Jay Parkinson and Design Observer founder Bill Drenttel.

This year's event takes place on October 15 in New York City, with speakers including Behance founder Scott Belsky, Collaborative Consumption author Rachel Botsman and Pencils of Promise founder Adam Braun, among others.

(For the next 48 hours, The Feast is offering a 30% off group discount – well worth it if you're in New York for the event.)
